Lurking among us in our cities and towns are older people who secretly experiment with truth. They have developed insight not shared by many younger than they.

Of course, the wise may not be easily recognizable as such. They do not walk around dispensing wisdom the way vending machines spew out coffee. In fact, they are probably reluctant to give any advice at all. The maxim about mystics holds here: "Those who say don't know; those who know don't say."
